SNOWPLOW AND SHOVEL.

Application filed. March 12, 1924;, Serial No. 698,808.

To all whom it may concern:

Be it known that I, JACOB A. NEWMAN, a citizen of the United States, residing at Madison, in the county of Dane and State of lVisconsin, have invented certain new and useful Improvements in Snowplows and Shovels, of which the following is a specification. I

My invention relates to machines for breaking up snow drifts and removing the snow from highways and'streets by cutting the snow ahead of a plow or transverse bar parallel with the street and forcing it backward upon and past the same within reach of an elevator; and the objects of my invention are, first, to assemble in practical working relation, cuttingordigging members above and ahead of a horizontal bar. or transverse platform, said members revolubly attached to and operated by a transverse multiple crank shaft revolubly journaled within suitable bearings secured to the main frame of the device; second, to construct a frame with a bar or narrow platform'extending across the front lower edge adapted to receive thesnow cut and forced backward by the cutting members and deliver it to an elevator; third, to provide an elevator which will take the snow from the bar and carry it upward to an adjustable transverse conveyor from which it will be deposited on either side of the road as desired; fourth, to have the cutting members and elevators and conveyors driven from a power unit mounted on the frame, but meansprovided by which theymay be driven from the r0 tary power pulley .upon the tractor which may be used to push the machine; fifth, to have the device hinged to the tractor and means provided by which it may be raised at the front end, so as to remove the upper portion of deep drifts and then lowered to the road for removing the balance; and sixth, to mount wheels upon adjustable arms at the front end of the frame to be used when'moving the machine over open roads.

I attain these objects by the mechanism shown in the accompanying drawing in whichi Fig. 1, is a plan;

Fig. 2, is a left side elevation;

Fig. 3, is a rear end elevation.

Similar numerals refer to similar parts throughout the several views.

The frame comprises side rails 1 vertical side posts 2 with cap cross beam 2* secured to the upper ends thereof, inclinedfront cor:-

ner posts 8 with capplate 4 connecting the top ends, side'beams 5connected to the cor 1 ner posts and extending backward'tot and beyond the posts 2 for mounting a conveyor thereon, lower rear side braces 6 extending from the lower side rails'l upward to the rear end of the side beams 5, lower front side braces 7 from the rails l forward to the corner posts 3, upper side braces 8 from front ends of beams 5 to the top of'posts 2, upper front side braces 9 from intersection of side beams 5 and posts2 to the top of the corner posts 3, cross beams 10 between the side rails 1, with cross ties 11 between the beams 5. 13 are journaled in boxes, 14 which are secured to the corner posts 3, said shafts have the crank arms disposedin alignment with each other and of equal gthI'OVV. Uponthe wrist pins of theshafts, suitable bearing Two multiple'crankshafts 12 and f boxes 15 are disposed, with flanges 16 adapted to be secured to vertical beams or shovel handles 17, shovelblades 18 are secured to and across the lower ends of each pair of handles, forming a downwardly and back wardly cutting or digging unit, any practical number of which may be employed on a machine. The two crank shafts 12 and 13 are revolubly connected together by suitable transmission means, preferably sprocket wheels 19 and chain '20. A transverse bar.

or narrow platform 210f sheet metal with upwardly extending flanges at each endis located atthe front end of the side rails 1 and bolted thereto, the front edge of the bar is parallel with the road and in operation just clears the same, but the rear edge is elevated sufficient to carry snow upward and conduct it to an elevator. An elevator 22 extending from side to side of the frame and securedthereto, has its lower end located just back and under the bar 21 andits upper end backward and above the rear portion of'side beams 5, and directly over a horizontal conveyor 23, whereby snow broken up by the shovels 18 and'forCed over if i the bar 21will be carried up the elevator 22'dropped upon conveyor 23 and carried to either side of the road by the conveyor,

the motion of which can be reversed as will be hereinafter explained. A power unit, preferably a gasolene engine .Zt-is secured to a platform 25 on the top andacross the rear end of side rails 1. A jack-shaft26 is journaled in boxes 27 secured to v the vertical posts 2 ;and isrevolubly operated from the 1 engine .by transmission means, preferably jack-shaft a sprocket wheel 34 is secured and a chain 35 leads upward to a similar wheel integral with a spur gear 36, both mounted revolubly on. a stud-pin 86 on'the side of the elevator 22the upper cross shaft of which is provided with a spur gear '37 which meshes with .gear '36, thereby revolubly connecting' thesengine with the said elevatorinproperrelation to carry the snow upward. A shaft 38 is located-under and acrossthe-xbeams 5 back of the vertical .posts 2 and j-ournaled in boxes 39, upon said shaft two bevel pinions 40 are loosely 'mounted and in mesh'wi-th a bevel gear 41 which is secured to a-vertical shaft 42, at-the top of the shaft 42 a. miter gear 48 issecured which meshes with a similar gear 44-which is secured to the innerv end ofa horizontal shaft 45 carrying sprocket wheels 46 upon which the conveyor chains 47 of the conveyor 23 are disposed. clutch knuckle 48 slidably mount-ed onthe shaft '38 and ada-ptedto engage jaws onthe inner surfaces of the bevel pinions 40 provides a 'means for reversing the motion of the conveyor before referred to. 'A shifting fork 49 operably attached to the knuckle" 48 and provided with a handlei50 is pivoted on a stud-pin 51 extending downward from the middle cross tie 11, said handle extending backward a distance desired for operating the-clutch back of the machine. The said conveyor 23 is ofcommontype two lines of sprocket chain secured to the ends andunder sides ofcross slats, and is driven by sprocket wheels engaging-the chains from the under side, the sprocket wheels as before explained to the cross shaft- 38, which is operably connected intermediate its length to the jack-shaft by gears 52, Atthe rear side and right end beneath the bottom of the conveyor a length of toothed rack :53 is secured, which meshes with a spur pinion 54 which is loosely disposed o-n'a stud-pin 55 secured adjacent the top of the angle plate '56, a universal cou pling 57 is attached to the pinion 54 and a rod '58 extends backward formanually operating the conveyor either to the right or left for depositing the snow as desired. The side frame of the conveyor comprises side boards and sills with necessary cross beams and is secured to two round rods 59 Y which curve downward from the ends ofthe sills for a. distance thence become parallel tothe sills, said rodss are slidabl y disposed between rollers 60 revolubly mounted on pinsfil through the top portion of the angle plates 5,;6 which are mounted on the top of the beams 5. by turning ,the rod 58 the conveyor may be moved to the right or left side of the ma- ;chine ItiS alsolplain that by moving the v handle 50 to the right or left, the movement of the conveyor will be reversed. .SfllQGS 62 areprovided at the. under front ends of the rails 1. V The truck wheels 133 mounted on an axle 64 secured :between arms "65' .adjusta'bly piv'otedqtov the rails,provide acmeans for transporting the machine over openroads.

Hinge beams 66 are connected to the rear ends of the rails for fastening awtractor back of the. maohine,.and cablesr67 attached to the posts 3 and over pulleys 618' when wound upon a winch will raise the front end ofthe machine hi ged1-at69.

' To operate the lmachine, -fasten by the It is therefore obvious that hinge beamsf66 to -thevfront end-of a tractor and push-into the snow, start the engine 24 which have a clutch. -interposed between it and the ackeshaft 'i1fJdesire d,- then the cutters will-cut downward" and/rbaclp I-Iaving thus described -my invention; I
